Abstract

Soil erosion causes a loss of nutrients in the soil and is evident in the agricultural areas of Batu City, primarily due to the steep or very steep topography. So it will affect the level of production. Determination of the effectiveness of observation was based on four classes of slope: 0-8%, 8-15%, 15-30%, and >30% at various altitudes: <1,100 m, 1,100-1,300 m, 1,300-1,500 m, 1,500-1,700 m, and >1,700 m above sea level 40 observation points. Geostatistical analysis with ArcMap software was conducted to determine the pattern of semivariograms. The results of this study indicated that the slope, altitude, and organic matter affect the yield of potatoes. The resulting formula is y = 11.845 - 0.258x1 + 0.007x2 + 2.454x3, where y is the potato productivity, x1 is slope, x2 is altitude, and x3 is the organic C, with r value is 0.87 and R2 value = 0.74. The highest potential production of potatoes in Bumiaji reached 33.06 t ha-1, and the lowest was only 7.12 t ha-1. Available land planted with potatoes can produce  35,891 t of potato, with average productivity reaching 24.6 t ha-1.

Abstract

This activity was carried out through the Community Service program by lecturers from Solo Christian Technology University (UKTS) in Ingasrejo Hamlet, Plesungan Village, Gondangrejo District, Karanganyar, Indonesia. The methods used include a pre-test, providing socialization material, and a post-test to evaluate the increase in participants' knowledge. Participation in this activity involved 20 people consisting of Rukun Warga (RW) administrators, Rukun Tetangga (RT) administrators, women from the Family Welfare Development Management (PKK), and local Youth Organization (Karangtaruna) administrators. The pre-test results showed that only 28.75% of participants had good knowledge of the 3R principles, while 42.5% were in the poor category. After socialization, the post-test results showed a significant increase where 73.75% of participants were in the good category and no participants were in the poor category.

Abstract

Kegiatan pengabdian kepada masyarakat ini bertujuan untuk mengoptimalkan pemanfaatan pekarangan rumah melalui pendampingan budidaya organik sebagai upaya meningkatkan ketahanan pangan keluarga di Desa Podosari. Metode pelaksanaan meliputi penyuluhan, pelatihan, serta pendampingan langsung kepada masyarakat sasaran. Evaluasi kegiatan dilakukan menggunakan metode pre-test dan post-test untuk mengukur peningkatan pengetahuan peserta. Kegiatan ini melibatkan 25 peserta yang terdiri dari ibu rumah tangga dan kelompok tani lokal. Hasil evaluasi menunjukkan adanya peningkatan pengetahuan peserta sebesar 40% setelah mengikuti rangkaian kegiatan. Selain itu, sebanyak 80% peserta mampu mengimplementasikan teknik budidaya organik di pekarangan rumah, seperti penanaman sayuran dan pemanfaatan limbah rumah tangga menjadi pupuk kompos. Pendampingan yang dilakukan juga berkontribusi terhadap peningkatan keterampilan peserta dalam pengelolaan tanaman secara berkelanjutan. Secara keseluruhan, program ini memberikan dampak positif terhadap peningkatan pemahaman dan kemandirian masyarakat dalam memenuhi kebutuhan pangan keluarga. Dengan demikian, optimalisasi pekarangan rumah berbasis budidaya organik dapat menjadi solusi efektif dalam mendukung ketahanan pangan rumah tangga di tingkat desa.
